The latest x86 fix can be found in git: http://git.denx.de/?p=ipipe-2.6.git;a=shortlog;h=refs/heads/ipipe-2.6.37-x86 ie. ipipe-2.6.37-x86 branch of git://git.denx.de/ipipe-2.6.git It's surely worth retrying with that version and latest Xenomai (maybe even 2.6.x git, though 2.5.x should contain all known fixes). Otherwise, please provide your .config.
